Answer:
Mean = 11.3 grams
Standard Deviation = 3.5 grams
Step-by-step explanation:
Mean is affected by change of origin but standard deviation is not affected. Hence the scale weighed items 1.5 grams affect only the mean not standard deviation. Hence, the mean for new food item is 12.8 - 1.5 = 11.3 grams as weight gain by 1.5 gram due to wrong calibration and the standard deviation remains the same as 3.5 grams.
Answer:
-2/3
Step-by-step explanation:
Since slope is just rise over run, find the y intercept and see how far it is from the x axis. If it goes down and is above \the x axis, then it is negative and if it is under the x axis, then it is positive. Then count how far the x intercept is. Same concept as the y intercept. Then, you put it as a fraction (y goes on top of x) and simplify to get your slope.
(-1,-2) is the answer because the solution to a System of Equations is where the two lines intersect.
